Researchers show how proteins slide along DNA to carry out vital biological processes A team of scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Harvard University, and the Indian Institute of Science has made a major step in understanding how molecules locate the genetic information in DNA that is necessary to carry out important biological processes. The research, published in the December 1, 2009 edition of Nature Structural & Molecular Biology,...

A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances." Adam Bogdanove, associate professor in plant pathology, was researching the molecular basis of bacterial diseases of rice when he and Matthew Moscou, a student in the bioinformatics and computation biology graduate program, discovered that the so-called TAL effector...

NEW YORK, Nov. 5 /PRNewswire/ -- Is homosexuality a choice, or is it part of our biological makeup? In the last few decades the topic has raged around the world from dinner tables to courtrooms. There have been very few scientific studies dedicated to identifying whether there is "gay gene" or attempting to clarify a scientific standard in this debate. The last major study was conducted 18 years ago by Harvard neuroscientist, Simon LeVay. His study involved research on the size of the...

A poll conducted for Britain's Science Museum on Wednesday named the X-ray the most important modern scientific achievement, beating out the Apollo spacecraft and DNA, AFP reported. The museum curators selected 10 of the greatest achievements in science, technology and engineering to be voted on by nearly 50,000 members of the public. The X-ray machine topped the votes, while the discovery of penicillin antibiotics came second, followed by the DNA double helix. Next was the Apollo 10 space...

Scientists have finally cracked the code of the three dimensional structure of the human genome. This could lead to a better understanding of the function and structures of cellular DNA and how it folds at scales that dwarf the double helix, according to a report published Thursday. "By breaking the genome into millions of pieces, we created a spatial map showing how close different parts are to one another," said Nynke van Berkum, one of two primary authors of the study, which appears in the...

Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix. Present in the cells of all living organisms, DNA is composed of two intertwined strands and contains the genetic "blueprint" through which all living organisms develop and function. Individual strands consist of nucleotides, which include a base, a sugar and a phosphate moiety....

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems. "My lab has been trying to find a way to deliver genetic-based drugs into cells." said Reineke. Scientists worldwide are using information from the human genome project as an...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
